@GET
@Path("{id}")
public Person getPerson(@PathParam("id")@Pattern(regexp = "[0-9]+", message = "The id must be a valid number")String id) {return persons.get(id);
}
person.id.notnull=The person id must not be null
person.id.pattern=The person id must be a valid number
person.name.size=The person name must be between {min} and {max} chars long
注意： {min}和{max}是指與消息關聯的約束的屬性。
一旦定義，這些消息就可以注入到驗證約束中，例如：
@POST
@Path("create")
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public Response createPerson(@FormParam("id")@NotNull(message = "{person.id.notnull}")@Pattern(regexp = "[0-9]+", message = "{person.id.pattern}")String id,@FormParam("name")@Size(min = 2, max = 50, message = "{person.name.size}")String name) {Person person = new Person();person.setId(Integer.valueOf(id));person.setName(name);persons.put(id, person);return Response.status(Response.Status.CREATED).entity(person).build();
}

當前無法在Eclipse上使用選項Run As >> JUnit Test ，因為必須存在名為jbossHome的系統屬性。 Eclipse不會從Surefire / Failsafe配置中讀取此屬性。 有沒有解決方法？
當使用ExceptionMapper<ValidationException> RESTEasy默認實現時，以application/xml媒體類型請求數據并發生驗證錯誤，將引發以下異常： org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure:Could not find MessageBodyWriter for response object of type:org.jboss.resteasy.api.validation.ViolationReport of media type:application/xml
